Running `target/debug/coreutils pr /dev/random`

Research direction
Start by reproducing the leak with cargo run pr /dev/random, then compare behavior with /dev/zero and /dev/full as reported. Locate the Rust implementation and tests for the pr command, and confirm the fix by processing these infinite streams without unbounded memory growth.
